How bad is it?

[Leadfooted]

So these little guys recently exploded on this rock. I can remove it and treat or frag it if needed. At the moment I can’t find other similar polyps anywhere but this one rock. These guys bad news or what?

im not sure what they are but if it was me id remove it if you don't like the look of it but do some research before on ways to remove it because it could be similar to aspacia and regrow if any is left. you can look here for hitchhiker ID's http://www.masa.asn.au/masawiki/index.php/Hitchhikers_Guide_to_the_Reef_Tank but I can't see anything that looks the same on the site. Goodluck

It’s not aptasia, almost looks like clove polyps

Does it look like this but maybe different color. I can’t really see from pix, old bad eyes

I couldn't find anything either but thanks. I actually like them, just worried they could sting other corals or get out of control. I'm leaning towards removing but I'd like to identify them first and see what methods may work the best to kill them for good.

are they moving e.g. when its night do they close their polyps and are they growing or spreading?

I have a few of those in my DT too

I think they’re different though. These that I’m concerned about lay more flat against the rock work.

Never thought to check. I will tonight and let you know.

Anthelia or sympdium??

I was leaning towards Sympdium but they appear to grow in the form of a skin with polyps. There’s no skin here and they don’t connect like other polyps I’m use to seeing.

okay good luck

lights off and they’re gone. No skin on the rocks, no sign at all. No they’ve hid, what’s this mean?

it means they are alive and can move and or retract into the rock. I'd look into trying to observe it coming out in the morning and talking to your LFS if you are worried

When I zoomed in on this I can finally see the polyps closed up. Some resemble the look of a closed zoa.

yea I haven't seen this before, id recommend talking to your LFS

 

[Dsnakes]

Seeing them closed, they look like the body of a digitate hydroid. However, the other picture doesn’t look like typical hydroid strings.... Odd for sure. #ReefSquad

Just realized they were open with lights on - definitely not digitate hydroids ;Facepalm

The original pic looks like some kind of clove polyp to me, but I have very little experience with them and whether they grow as mats or individually. The only concern I'd have is that they are likely to grow a lot faster than the nice corals they are close to and will over run them. I'd frag the rock and keep the unknown clove like stuff on a rock off in the sand until I was sure what they are and whether I'd want to keep them. They could be a real issue if they spread around the tank and also grow quickly.

They seemed to spread rather slowly across this rock in about a years time, not the fastest growers, kinda pretty though. I'm going to try and get a better pic today. I might take to LFS this afternoon, have him trim as much rock as possible. I'd still feel more comfortable dipping it in something that could maybe kill off any more polyps I can't see. Any suggestions?

 

[Ron Reefman]

If they are coral polyps, dipping it won't kill them off.

I've done spots I want killed by pulling the rock and dripping hydrogen peroxide on an area from an eye dropper. I just make sure that if I drip on much, it runs down where it won't do any extra damage.

Afterwords, just rinse with some water from the DT maybe?

Those are blue or purple clove polyps. They are not aggressive, but they can take up space around other corals.

Do you know if they can spread to other rock if it’s not attached. Let’s say I move this rock further into the sand away from the main rock, will the polyps remain only on this one rock? If so, I’m good with that. I might just kill the main colonies with some peroxide and keep them under control.
